Hydrogen is the most easily found element in the universe. It also has a simple structure consisting of a proton and an electron. In addition, it is possible to produce electrical energy from hydrogen in some different ways. As a result of gasification of fossil fuels such as natural gas and coal, hydrogen and carbon monoxide gas are released. Low cost is one of the most important advantages of this method. On the other hand, carbon monoxide gas formed in this process causes air pollution. It is possible to obtain hydrogen energy by using renewable energy sources. In this context, electricity obtained from renewable energy sources is used in the electrolysis of water. Hydrogen and sulfur can be separated because of electrolysis of hydrogen sulfide gas. It is possible to say that hydrogen has many advantages compared to other types of energy. First of all, the energy obtained from hydrogen is much richer than oil and natural gas. On the other hand, no carbon gas is released into the atmosphere due to the combustion of hydrogen. Only water is produced in this process. In other words, hydrogen is an extremely environmentally friendly form of energy. It is predicted that hydrogen will be used much more actively in the future due to its many important advantages such as being efficient, environmentally friendly, and safe. Many countries have taken important steps towards the use of hydrogen energy. In this process, it is vital to increase technological investments in hydrogen energy, which is gaining importance day by day. To achieve this goal, priority should be given to research and development investments for the acquisition, storage, and transportation of hydrogen. In this way, it will be possible to obtain and use hydrogen energy at a lower cost. This will take the countries one step further in their energy policies.
